I can’t say enough good things about JNA. The trainers here are top-notch – knowledgeable, motivating, and genuinely invested in your progress. What really sets them apart is how attentive they are when it comes to injuries or limitations. They don’t just push you through a workout; they take the time to understand what’s going on with your body and create modifications that let you train safely while still making progress. It’s clear they care about long-term health, not just short-term results. The atmosphere is always positive and supportive, and you really feel like part of a community. If you’re looking for a place that combines expert training with personal attention, JNA is the gym for you.

Joining JNA fitness was one of the best decisions I’ve made for my health & fitness journey. I’ve trialed many gyms over the course of the last 5 years, searching for a gym to help me improve my overall health and strength while simultaneously building a sustainable lifestyle routine - I’ve most definitely found that here. While I’ve only been at JNA for 3.5 months, I haven’t felt this good about myself and the strength in my body in years.

The team at JNA (Alex, Tara, & Julian) are absolutely incredible! The environment they’ve built at this gym is unlike any other in the best way. It’s a very welcoming and friendly community, with people of various levels of expertise & experience in the gym. After a few classes, I instantly felt like I belonged. Beginner or advanced, the team here makes sure to adjust the workouts to your comfortability/capability level but they’ll also push you to keep going to complete the workout because they want you to reach your goals. The classes are small group training, but with an individualized feel as each trainer will guide you with different weights or adaptations of the workout. With the knowledge they each individually bring to the table, you have a wealth of information to help you along your fitness/health journey and they’re always there to answer any questions you may have.

On top of all else, they’re very kind and caring people who happen to be your trainers. In this world, it’s rare to come across people who are genuine, kind and passionate about their job. You’re not just another body in this gym, you’re apart of something. I couldn’t be more grateful to Alex, Tara and Julian for helping me to get to where I am now. I highly recommend this gym to anyone at any fitness level because I promise you won’t find a better place with better people.

I can’t say enough about JNA Fitness. I have been a member for about one and a half years and it has been a really great experience. They have two locations, Wyckoff and Waldwick and I frequent the Wyckoff location. You workout in a small group setting but also get very individualized attention from the great team of Julian, Alex, and Tara. JNA keeps you accountable and they strive for healthy lifestyle changes. If I may say so, I truly feel they “give a damn.” I trialed a few other gyms prior to JNA and JNA takes the cake every time!!!! Thank you JNA and their team for inspiring me!! Well done!

JNA Fitness is hands down one of the best fitness decisions I’ve made. Trainers Alex, Julian, and Tara are incredible, they truly meet you at your level, which makes the space feel welcoming and not intimidating no matter where you’re starting from.

What really stood out to me is how intentional they are with new members. They don’t just sign you up and push you into a routine. Instead, they offer a trial period to make sure you feel comfortable and that it’s the right fit for you, something that sets them apart from many other gyms.

The facility is super clean, and the small group class sizes make it feel like you’re getting personal training attention even in a group setting. I’ve seen a real difference in my fitness level since joining, so much so that my husband noticed and signed up too!

Highly recommend to anyone looking for a supportive, knowledgeable, and no-pressure fitness community.

If you’re looking for a fitness boutique that combines personalized attention with effective workouts, JNA is a gem. This gym specializes in small class circuit training, which means you get hands-on guidance and real-time feedback from knowledgeable trainers who truly care about your progress.

The atmosphere is welcoming and non-intimidating, with a strong sense of community among members. Unlike overcrowded gyms, JNA keeps class sizes small, allowing for a more focused and supportive environment. You’re not just another face in the crowd—you’re part of a team.

My husband and I have been members here for almost 9years! Through three pregnancies, isolated injuries and overall aging, the amazing trainers have continued to adjust and readjust my expectations and workouts, to fit the season of life I am currently going through. Each of the trainers have the expertise and knowledge to help you set, achieve and exceed your goals. Even in group training, the trainers modify each workout to what is best for you and your body, pushing you to go up in weight or showing you a different way based on your capabilities. Some gyms can feel intimidating, but whether you're in the best or worst shape of you're life, JNA has a spot for you!

So next month marks 9 years since I joined JNA and it was the best decision. Not only am I stronger but at a time when women need to lift heavier weights and gain muscle it’s what my body needed. I feel amazing and joining prompted me to eventually start my eating, mind, body transformations as well. As for the staff? My trainers are family! They are not only knowledgeable but they listen and help you get where you need to be.

it’s been almost 2 years at JNA and I cannot speak more highly of the coaches here, especially my recommendation here for pregnancy and postpartum journey. They truly took such good care of me and my health during my fitness journey while pregnant. Even with a broken foot during my second trimester, I was back in the gym after 5 days with a boot and was able to keep up as much strength as I safely could with the help of Tara, Julian, & Alex! They specialized work outs for me with appropriate modifications and when anyone asks me how I’m able to run around and go on adventures with my newborn, I thank JNA! It’s the strength and muscle gains that is so important for a healthy body and postpartum recovery. Make the commitment for yourself and your mental and physical health will thank you ❣️

JNA is fantastic! I finally started exercising again after 1.5 years postpartum. I previously have done home workouts and orange theory. This time I was looking for a place that has a great community and where I can really get personalized training to rebuild my core and get stronger. JNA fitness has been amazing! The trainers really care about you as a person and the classes are awesome, always varied and the time flies by. I love their flexibility with our schedules and the 45 min workouts are great. When I started, I had a 1 on 1 session with Alex and he took the time to learn about my goals and expectations. I was never a morning person but I find myself being excited about working out at 6am with these guys. Shoutout to Alex, Tara and Julian for your kindness and support. I highly recommend giving JNA a try! You will find a welcoming environment and excellent workouts with knowledgeable staff who take the time to get to know you and help you succeed in your health and fitness goals.

I used to dread exercising, but JNA has been a game changer for me! I joined 4 years ago in hopes of getting into a more regular workout routine, but have gotten so much more than I could have imagined. The trainers are incredibly personable— they care about me as a person—not just my general health goals, but also my life. The workouts are carefully crafted to be challenging but also realistic, and I love that all I need to do is show up— I don’t have to think. I always leave JNA feeling strong, encouraged, and ready to conquer anything. I can’t thank JNA enough for changing my mindset around working out and taking care of body and mind.

P.S. Their playlists and challenges throughout the year are a great way they mix things up and keep things fun!

We can't say enough good things about JNA Fitness! From the moment we walked in 6 1/2 years ago, we felt welcomed and supported by the incredible staff and trainers.

The facility itself is top-notch, with more than enough equipment and a clean, motivating environment. But what truly sets this gym apart are the trainers. Each one is exceptionally knowledgeable, enthusiastic, and dedicated to helping you reach your fitness goals. Whether you're a beginner or have worked out your entire life like me, they tailor their approach to fit your individual needs and make each session enjoyable. The music they play is very motivating and during the summer they have air conditioning!

Special shout-out to TARA and ALEX who always pushes me and my husband to do our best and makes every workout challenging yet fun! We've seen tremendous progress since joining, and owe it all to their expertise and encouragement.

Thank you JNA Fitness, for being a place where we not only get stronger but also feel like part of a community. If you're looking for a gym that genuinely cares about your well-being and fitness journey, look no further!

JNA deserves more than 5 stars! I went to cheap gyms on and off for years but lacked motivation and ideas for balanced workouts. I found JNA through a friend 6 years ago and never looked back. I stay because I get to show up and the best trainers I could ask for take over. It may not be 1 on 1 personal training, but it is incredibly personal. They know me as a person, where I am at physically and how to push me individually, all while doing the same thing for 5 or 6 other people at the same time. I am proud to call them my friends, and simply put I love JNA!!

This is NOT a gym. This is a fitness training experience that specializes in 1:1 personal training sessions or shared group personal training classes (no more than 6 students) that is 100% worth canceling your gym membership for.

As a past fitness professional who really enjoys strength and weight training, I also found myself becoming less and less motivated to push myself as I’m now in my mid-30s. I absolutely LOVE the coaches here and they all bring something different to the table by designing a 45 minute circuit that hits the whole body and is SAFE to do. They do not push you in a way that sacrifices on form and also cater to any structural weaknesses by giving modifications for those who need it. I have been going regularly 2x a week religiously since January 2nd and it’s amazing how much better my body is feeling and how much stronger it’s getting. Not to mention my clothes are fitting better too. No idea if I lost weight because screw scales!

The entire staff also makes you feel welcomed and at home the minute you walk through their doors. Shoutouts to Coach Alex, KJ, and Tara who are the best of the best! Btw they offer even more personalized services and have another location 2 towns away in Waldwick that you can attend as well!

Even before I stepped into JNA, I knew this place was special. Tara messaged with me and set up a free consultation, which turned out to be an awesome 45 minute training session. She even took the time to explain exactly how to get there and where to park. I could tell right away that this is a place that cares about their members. Joe and Alina, the owners, and the other trainers know EVERY SINGLE member by name and make a point to come say hi, give a fist bump, and check in every time you walk in. You won't meet nicer people anywhere. The classes are KILLER: always fun, always changing, always challenging. The trainers are knowledgeable and can help modify any exercise to your level. This is the first place I've ever gone where I said I have diastasis recti and not only did they know exactly what I was talking about, but had experience with it and suggested modifications. The space and all the equipment is impeccably clean. They also go above and beyond to do special things for their members: in the 5 weeks I've been there they had a park workout, a meetup at Abma's farm, a nighttime glow workout with lightsticks to benefit a cancer charity, and a huge Memorial Day workout where friends and family were welcomed, complete with after workout party and treats. If you're looking for a great workout, community, and atmosphere, look no further!
